HINGE.

SPECIFICATION forming part of Letters Patent N 0. 761,969, dated June '7, 1904. Applicatioii'filed December 14-, 1903. Serial No. 185,105. (No nioclel.) 7

T0 (zZZ whom it may concern.-

Be it known that I, W LLIAM J. KEENE, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Hinges, of which the following is a full, clear, andexact description.

This invention, while applicable to hinges of various other styles, is designed more particularly for the improvement of that class of hinges known as double-acting spring hinges, which are intended for use upon heavy doors. An example of this style of hinge is illustrated in Letters, Patent No. 620,933, granted to Joseph Keene March 14:, 1899.

In the construction of the highergrade spring-hinges for sustaining heavy doors it has heretofore been customary to form the hinge of'bronze, brass, or like ornamental material or, as in the Keene patent he-reinbefore mentioned, to form the hinge of sheet-steel suitably bronzed or brass-plated or otherwise ornamented. An objection to the manufacture of this style of hinge entirely from bronze or brass metal is twofoldviz., the great ex pense of the metal and, second, its lack of strength. On the other hand, the hinge formed of sheet-steel, as in the Keene patent, while having the requisite strength, is objectionable because of the difficulty experienced in giving to it a durable ornamental coating.

My invention has for its object to provide a spring hinge having the advantages of strength and economy incident to a hingesuch, for example, as shown in the Keene patentand having also the advantage of a durable highly ornamental appearance incidentto hinges made from solid castings or sheet metal of bronze, brass, or like expensive metal.v

To this end the invention consists, primarily, in forming a hinge-body of inferior metal, preferably sheet-steel, and thereafter inclosing said body within a veneer or jacket drawn from plate metal surrounded and attached to the body of inferior metal.

The invention consists also in details of improvement, all of which will hereinafter appear from the following description and drawings, forming a part thereof. 7

- Figure 1 is a detail View of the drawn shell, jacket, or veneer for inclosing the body of the hinge. Fig. 2 is a view of the finished hingebody with the jacket thereon. Fig. 3 is a view in horizontal section on line 3 3 of Fig.

2. Fig. 4-is a view in vertical section on line 4 4 of Fig. 2. Fig. 5 is a detail view, upon an enlarged scale,showing a portion of the upper edge of the jacket. Fig. 6 is-a perspective view of the upper portion of the body with the jacket thereon, partly in section.

The body of the hinge is preferably formed from a plate of sheet-steel in the manner set forth in Keene patent, No. 620,933, above mentionedthat is to say, a sheet of steel is suitably bent by dies to form the barrels a a and the connecting-web (6 The ends of the barrels a a of the hinge-body and the ends of the connecting-web a willbe covered by a reinforcing-cap C, as shown in the Keene patent. After the body of the hinge has been formed-for example, as in the Keene patent aforesaid-a tubular jacket or veneer D will be slipped over the hinge-body, completely covering the body from end to end. This jacket'l) is drawn from sheet brass, bronze, or like ornamental metal and of such thickness as to stand the wear and tear and constant polishing to which hinges of this class are commonly subjected. The jacket D may be formed from a section of seamless tubing rolled to the shape shown in Fig. 1 or may be drawn from a plate-metal sheet or many other suitable manner; In practice the central portion a and barrels a a of the hinge-body will be formed from sheet-steel, as in Keene patent, No. 620,933, above mentioned, and reinforce cap-plate C, having cylindrical ends 0, will be set over the central portion a and the ends of the barrels a a, asin said patent, this capplate C being firmly forced over the ends of the hinge-bod y. The barrels a, a of the hingebody will have their upper and lower ends reduced cylindrical ly, as in the above-mentioned Keene patent, to receive the cylindrical portions 0 of the cap-plate C, so that when the cap is in place upon each end of the hinge body the cylindrical portion 0 will become practically flush with the body portions of the barrels a a.

In making the jacket D, I prefer to form the flat sections (Z, that cover the web a of the hinge-body, of the same length as the cylindrical portions d, that cover the barrels (1 (1/ of the hinge-body, as the ends of the webs or plates (Z will be turned down over the edges of the reinforcing-caps C, as shown in Figs. 2, 4, and 5 of the drawings. The edges of the cylindrical portion (Z of the jacket D are left unbent, as these edges will be covered by the bushings (not shown) that ordinarily set upon the ends of the barrels (m of the hingebody. If the edges of the flat portions (Z (Z of the jacket were parallel throughout with the ends of the cylindrical portions (Z 1, it would be found that when the edges of the flat portions (Z (Z were turned over the reinforcing-caps C there would be uncovered portions of the reinforcing-caps immediately adjacent the cylindrical portions (Z (Z of the jacket. To avoid this, I form those portions of the plates (Z (Z of the jacket adjacent the barrels (Z d with extensions or lips (Z which when the edges of the plain surfaces (Z (Z are bent over will come snugly against the walls of the cylindrical portions of the hinge-bod y, and thus completely cover those parts of the reinforcing-cap C adjacent the barrels of the hinge-body, as clearly shown in Figs. 2 and 5 of the drawings.

In applying the jacket D to the body of the hinge after the cap-plates C have been set in place thereon, as above described, the jacket D will be slipped over the hinge-bod y, and by suitable dies the edges of the central portions (Z (Z of the jacket will be bent over the central portions of the cap-plates C. IV hen the dies thus bend over the edges of the central portions (:Z (Z of the jacket, it will be found that a very slight space is left between the opposing edges of the central portions (1d of the jacket, and into this space solder a will be run, and the opposing edges of the central portions (Z (Z of the jacket will then be pressed together by a suitable tool, so that as the solder sets the edges will be united, forming practically a continuous joint along the top and bottom of the central portions of the hinge-body. At the same time the lips or extensions (Z being bent over and around the adjacent cylindrical portions 0 of the cap-plates will till the spaces at such points, so as to leave no unbroken or open spaces in the jacket about these cylindrical portions of the cap-plates. The exposed portions of the hinge-body will thus be completely covered by the bronze or sheet-metal jacket, so that the finished hinge, while possessing all the strength of the sheet-steel hinge shown in the Keene patent aforesaid,

has all the beauty of appearance and durability incident to the hinges made from solid metal of bronze or like material. The depression of the jacket along the lines (1' not only serves to give an ornamental effect to the hinge, but by thus causing the jacket to conform closely to the surface of the body of the hinge the danger of denting or marring the jacket is avoided.

It is manifest that the precise details above set out may be varied withoutdeparture from the spirit of the invention and that the invention may be applied to hinge-bodies of other styles than the steel hinge-body illustrated in the Keene patent aforesaid.

Having thus described my invention, \\'hat I claim as new, and desire to secure by Imtters Patent, is

1. A hinge-body comprising an inner portion of inferior metal and an outer seamless sheet-metal jacketsurrounding said inner portion and secured thereto.

2. A hinge-body comprising an inner portion of inferior metal having a barrel and a web portion and an outer seamless sheet-metal jacket surrounding said barrel and web portions.

A hinge-body comprising an inner portion of inferior metal having barrels and a connecting-web and a jacket of sheet metal surrounding said inner portion, said jacket having open-ended barrels fitting around the barrels of the inner portion and having eonnecting-sections between said barrels, the ends of said connecting-sections being closed over the ends of the web of said inner portion.

4. A hinge-body comprising an inner portion of inferior metal having barrels and a connecting-web and a jacket of sheet metal surrounding said inner portion, said jacket having open-ended barrels fitting around the barrels of the inner portion and having connecting-sections between said barrels, the ends of said connecting-sections being provided with lips or extensions adjacent the cylindrical parts of the jacket, said ends of the connecting-sections being folded over the ends of the connecting-web of said inner portion of the hinge-body.

A hinge-body comprising an inner portion of inferior metal having barrels and a connecting-web and an outer sheet-metal jacket having cylindrical parts setting around the barrels of said inner portion and plain sections arranged opposite the web of said inner portion, the ends of said plain sections of the jacket being folded over and united to the ends of the web of the hinge-body.
